According to closed informants and associates of Seratuhlis Firanelli, he/she (Seratuhlis) once served as a warrant officer and mech ace in the now defunct military group of 39th Blackwatch MHTF. He/she then left the group in favor of Artemis, another defunct military group, after a series of arguments between Sparda Aridian and Fooks Bueler caused much drama within Blackwatch. Seratuhlis served within Artemis as the general of its engineering division, creating Artemis's first prototype mech avatars and armor. Unfortunately, for Seratuhlis, DaveyDarkstrider Oh, Founder of Artemis, cooperated with Failius Falta in order to shift from Artemis into a Warhammer 40k space marine based group called the First Sons. Seratuhlis then defuncted in favor of Vanguard, serving as a Hauptmann (captain).
